A 200 g rod hangs from a pin located at 20 cm from the left edge of the rod.?

A 200 g rod hangs from a pin located at 20 cm from the left edge of the rod. There is 300g mass hanging from the rod at a distance of 50 cm from the left edge of the rod. If the mass of the rod is not neglected, what is the net torque about the point at which the pin is located?
